Measuring Bend Angle using a Flex Sensor Circuit

Last updated on 1 July 2026 by Admin-Lavi Leave a Comment

Flex sensor is a small strip that changes resistance when we bend it. When the sensor remains straight, it has low resistance and when it bends, its resistance increases; also many robots, gloves, gaming devices, medical tools, wearables, and other projects use this sensor. Additionally, sensor works simple, as with more bend it gives more […]
